Candidatis Anammoxoglobus propionicus

Candidatis "Anammoxoglobus propionicus" is an anammox (anaerobic ammonium oxidation) bacteria isolated from a landfill leachate. Anammoxoglobus is one of two genera capable of anammox within the phylum Planctomycetes, the other being Brocadia. . Anammox bacteria are of interest to many researchers due to its ability to reduce nitrite while oxidizing ammonium, producing nitrogen gas and and water (NH4+ + NO2− → N2 + 2H2O). This process occurs naturally and also in human structures, such as waste water treatment plants.

A unique structure that characterizes anammox bacteria is its anamoxosome. This is where the anaerobic ammonium oxidation reaction occurs. Annamox bacteria have a slow growth rate and can make isolation processes difficult.

In 2014 an experiment successfully enriched Ca. "Anammoxoglobus propionicus" within a sample of sludge from a landfill leachate anaerobic treatment system. Researchers started with an enrichment containing of 1.8 ± 0.6% Ca. "Anammoxoglobus propionicus", and after 481 days the observed fluorescence in situ hybridization (FISH) results showed an enrichment amount of 65 ± 5%. During the process Ca. "Anammoxoglobus propionicus" removed ammonia (70 mg-N/L) and nitrite (90 mg-N/L) at a stable rate, and the total nitrogen removal efficiency was stable at 95%.
